Lance - Lots of possibilities of names for the two small dark ducks. If they are quite a bit smaller than the blk& white ducks check out pied-billed grebe. Grebes are common in OH duing spring migration. However they usually travel single.

As Newbee says the black and whites are most likely lesser scaups who are divers and common here during spring stop-overs. The darker ones could be the females; you probably have two pair. Scaups often travel in small or medium sized groups. I will have those same species of duck in northern OH in a week or two. Get them every spring just after ice out.

FYI: It's Canada goose singular, Canada geese plural. Canadas is vernacular or local slang.
